I think the only thing Swift has in common with C++ are the slow compile
times, or else I'm missing something. Interface Builder is even further.

But maybe you mean that it could use a similar (memoization) approach ?

We had a similar question before, but I think that it went unanswered...

I think it *could* probably be done, but it would look a lot different.


The first step would be to get a list of all the file dependencies.
There is no preprocessor, so no need to worry about (just modules)

Apparently there is a "swiftc -emit-dependencies" (output depends),
maybe the .d files could be parsed to generate something useful ?

Might be some similarities to https://github.com/ccache/ccache/pull/130


And it would probably make for a separate program/project, as well...

Even the Objective-C stuff (i.e. modules) is getting hard to support.
